Abstract

It has been demonstrated that the protonic acidity is essential for the reduction of nitrogen monoxide by methane over Pd ion-exchanged H-ZSM-5 (Pd/HZ), by the comparison of the reaction with that over Pd ion-exchanged Na-ZSM-5 (Pd/NaZ), having similar dispersion of palladium. It was further shown that the difference between the active Pd/HZ and the inactive Pd/NaZ is present in the reaction between NO2 and CH4.
